Recording medium storing video game program and video game device

Abstract

The player gives a change in the input through a touch operation to a character pattern P 2 displayed on a second display screen 12 a covered by a touch panel. The character pattern P 2 is associated with a player character P 1 displayed on a first display screen 11 a , and is displayed on a larger scale than the player character P 1 . The player character P 1 is moved according to the change in the input. Thus, a video game is provided that is played on a dual-screen video game device with a novel operation in which the player can accurately specify an intended position.
